Answer:

5/15

Step-by-step explanation:

Out of 15, 5 are yellow. Converted to a fraction this will be 5/15. Hope this helps!! :)

Answer:

1/3

Step-by-step explanation:

Take the total number of socks and compare it to the number of yellow socks. 15 and 5. Now divide the total by the specified group (yellow socks), by doing so, you get 3.

Every 1 in 3 socks is yellow, meaning the chance of picking a yellow sock at random is 1/3.

Answer:

neither when you multiply them you get -3y+15 not 12

Answer:

2) 0.0914

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

A survey of 114 drivers is performed and 62 people say they will not drive until all passengers in the vehicle are buckled up.

This means that [tex]n = 114, \pi = \frac{62}{114} = 0.5439[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What would be the margin error for this confidence interval?

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 1.96\sqrt{\frac{0.5439*0.4561}{114}}[/tex]

[tex]M = 0.0914[/tex]

Thus the margin of error is 0.0914, option 2).

Answer:

2400 + (0.05X) = 2900

Therefore, the amount of sales that Liz will have to make to meet her goal is $ 10,000.

Step-by-step explanation:

Since Liz earns a salary of $ 2,400 per month, plus a commission of 5% of her sales, and she wants to earn at least  $ 2,900 this month, to find amounts of sales that will meet her goal, the following equation must be solved:

5/100 = 0.05

2400 + (0.05X) = 2900

0.05X = 2900 - 2400

0.05X = 500

X = 500 / 0.05

X = 10,000

Therefore, the amount of sales that Liz will have to make to meet her goal is $ 10,000.

14 and 1

Explanation:

14 + 14 + 1 + 1 = 30

14 x 1 = 14

The perimeter is the sum of all 4 sides. Divide the perimeter in half fo the some of one length and one width:

Length + width = 15

Area is length x width

Find 2 numbers that when added equal 15 but when multiplied equal 14

15 + 0 = 15, 15 x 0 = 0

14 + 1 = 15, 14 x 1 = 14

The answer is 14 ft long by 1 ft wide

OPTION D is the correct answer

Answer:

-2 > -5

Step-by-step explanation:

Since -2 is greater than -5 we use the greater-than sign to represent this relationship.

Answer:

x = 5

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.

Add 3 and subtract 2x from both sides of the equation:

4x (-2x) - 3 (+3) = 2x (-2x) + 7 (+3)

4x - 2x = 7 + 3

2x = 10

Next, isolate the x by dividing 2 from both sides of the equation:

(2x)/2 = (10)/2

x = 10/2

x = 5

5 is your answer for x.

Answer:

x=5

Step-by-step explanation:

4x-3=2x+7

Subtract 2x from each side

4x-2x-3=2x-2x+7

2x -3 = 7

Add 3 to each side

2x-3+3=7+3

2x = 10

Divide by 2

2x/2 =10/2

x = 5

Answer:

[tex]f(x) = 6x ^{2} + 12x - 7 \\ x = \frac{ - 6 + \sqrt{78} }{6} \: , - \frac{ - 6 - \sqrt{78} }{6} [/tex]

Given:

The quadratic function is:

[tex]f(x)=6x^2+12x-7[/tex]

To find:

The zeros of the quadratic function.

Solution:

Quadratic formula: If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then zeros of the quadratic equation are:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]f(x)=6x^2+12x-7[/tex]

For zeros, [tex]f(x)=0[/tex].

[tex]6x^2+12x-7=0[/tex]

Here, [tex]a=6,b=12,c=-7[/tex]. Using quadratic formula, we get

[tex]x=\dfrac{-12\pm \sqrt{(12)^2-4(6)(-7)}}{2(6)}[/tex]

[tex]x=\dfrac{-12\pm \sqrt{144+168}}{12}[/tex]

[tex]x=\dfrac{-12\pm \sqrt{312}}{12}[/tex]

[tex]x=\dfrac{-12\pm 17.6635}{12}[/tex]

Now,

[tex]x=\dfrac{-12+17.6635}{12}[/tex] and [tex]x=\dfrac{-12-17.6635}{12}[/tex]

[tex]x=0.47195833...[/tex] and [tex]x=-2.47195833...[/tex]

[tex]x\approx 0.472[/tex] and [tex]x\approx -2.472[/tex]

Therefore, the zeros of the given quadratic function are 0.472 and -2.472.

Answer:

5.34

Step-by-step explanation:

f(-2) requires that we change x with -2 in the f(x) equation, yet the f(x) =5.34 so it has no x, therefore f(-2) =5.34

Answer:

8.7 m

Step-by-step explanation:

Hi there!

[tex]5^2+h^2=10^2[/tex]

To find the height of the building, we need to isolate h on one side of the equal sign. We will do this by performing inverse operations to both sides (ex. the inverse of addition is subtraction, the inverse of multiplication is division, etc.)

Firstly, we can simplify both sides by squaring 5 and 10:

[tex]25+h^2=100[/tex]

Now subtract both sides by 25 to cancel it out on the left side and isolate h²:

[tex]25+h^2-25=100-25\\h^2=75[/tex]

Now, take the square root of both sides to isolate h:

[tex]\sqrt{h^2} =\sqrt{75} \\h=8.7[/tex]

Therefore, the height of the building is 8.7 m when rounded to the nearest tenth.

I hope this helps!

Answer:

Angle 2 = 124 degrees

Step-by-step explanation:

Angles 1 and 2 are corresponding angles since the two lines are parallel.

We can put both numbers into an equation.

3x + 25 = 2x + 58

Subtract both sides by 2x which will give:

x + 25 = 58

Now, we can solve for x, which is:

x = 58-25 = 33

Put back x = 33 into angle 2.

Hence, angle 2 is 2*33 + 58 = 124

Answer:

m∠2 = 124 degrees

Step-by-step explanation:

By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;

3x + 25 = 2x + 58

x + 25 = 58

x = 58 - 25

x = 33

Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;

∠2 = 2(33) + 58

∠2 = 66 + 58

∠2 = 124

Therefore m∠2 = 124 degrees.

Answer:

x = 46.8

Step-by-step explanation:

I assume you are trying to find the value of x.

[tex]5x=234.[/tex]

To find x, divide the answer by the coefficient. The quotient is the value of 'x.'

[tex]234/5=46.8[/tex]

Therefore, 46.8 is the value of x.

Remember: Whenever you see a coefficient and a variable together—5x, 7y, 3t—this means to multiply them.
